Reduce image size in group

Hi there,

I took pictures of hundreds of product using a digital camera, and the image size is around 140k (640x480). Is there a software that can reduce the image size at one go? I mean I dont have to reduce them one by one. I still need the image to be 640x480, just reduce them to suit web use.

thanks very much

Here are a few programs (including the free ones) that should help you with your batch compression task:
XnView
FastStone Photo Resizer
IrfanView
Batch JPG Compress
and
a list of batch compress programs

thanks Varelse!
